[YevgeniyShunevych]

1. Create Report<TOwner> class that wraps ILogManager and duplicates its methods but with returning of TOwner. Is useful for reporting inside tests within a fluent chain.

2. Add property to PageObject<TOwner>:

   public Report<TOwner> Report { get; }

Usage

Go.To<SomePage>().
    Report.Trace("tracemessage").
    Report.Debug("debugmessage").
    Report.Info("infomessage").
    Report.Warn("warnmessage").
    Report.Error(errorException).
    Report.Error("errormessage", errorException).
    Report.Error("errormessage", exceptionStackTrace).
    Report.Fatal(fatalException).
    Report.Fatal("fatalmessage", fatalException).

    Report.Start("Some section").
    // Do something within section.
    Report.EndSection().

    Report.Screenshot().
    Report.Screenshot("sometitle");
